Will you upgrade to Windows 8 when it is released? Why?
Please define "works". Technically Vista and ME "worked". Microsoft has a history of: Release GOOD OS » Release BAD OS » Release GOOD OS.It's not a Vista. Or a Windows ME.
It actually works.
By that very definition, Vista didn't work.Define "works". Vista also worked, albeit only some of the time...
So it is basically the same as Vista -> 7, more like a patch with some UI changes that they charge for, and some new features.By that very definition, Vista didn't work.
Windows 8 is stable and performs well. The overall performance is the same as Windows 7 - maybe even marginally better when you consider the optimisations made with the UEFI booting and SSDs. From cold boot to start screen in around 6 seconds. That's its best feature.
Unfortunately though, there isn't much else. So, that's why it probably won't be successful. So it will fail, just not in the same way as Vista or ME.
